About the city gas fast opening and closing gate valve
MZ series city gas fast opening and closing gate valve, suitable for medium: blast furnace gas, coke oven gas, generator gas, water gas, oil gas and other sewage gas, as well as liquefied gas, natural gas, mine gas and other clean gas. It is mainly used in gas production and city gas transmission and distribution pipelines in coal gasification, metallurgy and coking industries.
The transmission thread of the dark rod gate valve is located inside the body. During the opening and closing process, the valve stem only rotates, and the gate plate rises and falls in the valve body. Therefore, the height of the valve is small. The dark rod gate valve is usually equipped with an opening and closing position indicator above the valve cover to be suitable for environments with small space such as ships and trenches and large dust content.
Features:
1. There is a sewage tank at the bottom of the valve, which is convenient for cleaning dirt and impurities, and can smoothly pass the pipeline cleaner.
2. The valve stem adopts large guide thread drive, which can realize quick opening and closing.
3. It adopts high-performance filler with minimal friction, automatic lubrication, and resistance to gas and various corrosive gases. It is flexible in operation and reliable in sealing.
4, excellent sealing performance, can automatically remove the dirt on the sealing surface during operation, and maintain a tight seal.
5. The fluid resistance is small. The internal medium passage of the gate valve body is straight-through, and the flow direction of the medium does not change when the medium flows through the gate valve, so the flow resistance is small.
6, the opening and closing is more labor-saving. The direction of movement of the shutter during opening and closing is perpendicular to the direction of flow of the medium. Compared with the stop valve, the opening and closing of the gate valve is more labor-saving.
7. The flow direction of the medium is generally not limited. The medium can flow through any direction on both sides of the gate valve, and can achieve the purpose of turning on or off. Easy to install, suitable for use in pipes where the flow direction of the media may change.
